According to the Oxford English Dictionary, the nose is “the part projecting above the mouth on the face of a person or animal, containing the nostrils and used for breathing and smelling.” And the description admittedly doesn’t sound very special. But this central facial feature does so much; it can even potentially sniff out life-threatening health conditions that you didn’t know you have.
Before 2014 scientists had estimated that the human nose could discern about 10,000 scents. However, researchers held onto a feeling that the sniffer could actually distinguish many more than that; they just needed a testing method to prove the theory. So in 2014 a team presented their research, which had been conducted with the help of odorous molecules, and it revealed something spectacular about our noses.
